A second end of the second routing path is coupled to an output of the amplifier. Only one of the switches is turned off and a remainder of the switches are turned on. Capacitors are coupled in parallel between the first routing path and the second routing path. A first end of each of the capacitors is coupled to the first routing path. A second end of each of the capacitors is coupled to the second routing path.
